audiomxd high memory allocation port allocation CPU time

Apple Community.

audiomxd Memory and CPU screenshots

In February 2025, I bought a Mac Mini then migrated from my iMac (Retina 5K, 27-inch, Late 2015) to my current Mac Mini M4 Pro. The Mac Mini is probably running Rosetta.

About: Mac Mini 2024 M4 Pro. 64 GB Memory. macOS Sequoia 15.4.1. Apple Pro Display XDR with NO MICROPHONE and NO SPEAKER. No Audio app. No VST plugins.

The Apple Pro Display XDR is connected with an Apple Thunderbolt 5 cable to one of the three Thunderbolt 5 ports in back.

An external Lacie backup drive is connected with an Apple Thunderbolt 4 cable to one of the three Thunderbolt 5 ports in back. Time Machine backs up the Mac Mini M4 Pro once a week.

Feedback - Mac mini - Apple

Feedback report 6 on the audiomdx memory leak.

2025-04-26 12.23PM 1.36 GB 102,386 Ports.

2025-04-27 10.14AM 1.52 GB 130,067 Ports.

On 2025.04.27 I changed some settings then Shut Down.

Apple > System Settings > Apple Intelligence and Siri >

Apple Intelligence: OFF

Siri: OFF

Adobe Elements 2021 Organizer > Preferences > Media-Analysis >

Generate Auto Creations: OFF.

On 2025.04.29 I uninstalled an Adobe desktop app the Shut Down.

Uninstall the Creative Cloud desktop app

On 25.05.02 I changed some settings then Shut Down.

Settings > Desktop & Dock > Drag Windows to menu bar to fill screen OFF

On 2025.05.03 here are Activity Monitor screenshots of CPU Time and of Memory Allocation.

2025.05.03 12:49 PM audiomxd CPU Time 20:02:08.10

2025.05.03 12:49 PM audiomxd Memory 770.2 MB 39,904 Ports.

Usually, I Logout after each time I use the Mac Mini.

Occasionally, I only Lock the Screen.

Why is Memory allocated, but not freed after closing the app that was using the Memory?

Why does audiomxd need an ever-increasing Memory Allocation to manage the internal speaker on a Mac Mini? I have no external speaker or microphone.

Activity Monitor provides an important capability in identification of apps that are experiencing concerning trends in CPU Time, memory usage, and ports.

EtreCheckPro is very useful in identification and removal of likely suspects which may be causing the concerning trends.

Thank you, BDAqua for troubleshooting this problem.

Thank you for the suggestion, den.thed.

Yes, AirPlay Receiver has been OFF since 2025-06-10.

I'm very grateful for your time.

Earlier today Migration Assistant transferred information from a Time Machine Backup with:

NO Applications

NO Other Files & Folders

NO System & Network

audiomxd continues to allocate increasing amounts of Memory and increasing numbers of Ports.

The following additional information may be relevant.

-----

The Macintosh HD categorizes a significant amouint of storage memory as "Other Users & Shared". I'm the only User. The Guest User is OFF.

-----

System Data finishes Calculating for a brief period, and, within seconds, begins Calculating again. I may let it continue Calculating for a few hours to see if it completes its second calculation.

I overwrote my user name with "Administrator Name"

Does anyone viewing this thread have a similar configuration with audiomxd using this much Memory and this many Ports?

Mac mini M4 Pro. Apple Pro Display XDR. Magic keyboard. Magic Mouse. LaCie external HD.

The display has NO microphone, NO speaker, (no audio), NO camera.

The Mac Mini M4 Pro macOS 15.6.1 has only its internal speakers.

The LaCie external HD has NO speaker or microphone.
